Speaking of the tax exempt "subsidy" (not taxing someone isn't a subsidy) my pastor shocked me in a good way several months ago by saying he would not let the government dictate what he preached as the Gospel. He said if they threatened to take his tax exempt status, he'd say "take it!"
The "Theophobes'" constant threats and expressions of hatred is to "tax the churches" nowadays. But, predictably, revoking the tax exempt status of churches that won't bow before the state agenda won't placate the raving anarchists. They won't stop their vicious attacks until the church is pounded into dust. The "tax-exempt" excuse is just that - an excuse.
Pastors and their congregations need to get informed on the actual laws concerning tax exempt status.
You can give a whole sermon on politics, endorsing a particular candidate. If that is one out of 52 sermons given in a year, or better yet, one out of 100 (if you have Wednesday services and special services on holidays),
then your church would owe taxes on one dollar out of $100 for the time spent on the non-tax exempt activity.
It is a chain to the state. Soon we will either have to break that chain, or go along with what the state wants. You can't have it both ways.
